FEED-TABLE FOR R LLlNG-MILLS.

SPECIFICATION forming part of Letters Patent No. 572,168, dated December1, '1896.

A li ation fil d June 6, 1896. Serial No. 594,477. (No model.)

To all whom it may concern.-

Be it known that I, SIGMUND V. HUBER, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State of Ohio,haveinvented or discovered certain new and useful Improvements in Feed-Tables for Rolling-Mills, of which improvements the following is aspecification.

The invention described herein has for its object a construction offeed-table for rollingmills designed to be used by preference inconnection with a feed-table described and shown in an application ofeven date herewith. r

In general terms the invention consists in a construction andarrangement of mechanism and devices for receiving an article from therolls, shifting it vertically and laterally, and returning it to therolls, all as more fully hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1 is a top plan view of my improved receiving and delivery table.Fig. 2 is a sectional plan of the same, the plane of section beingindicated by the line of section II II, Fig. 5. Figs. 3 and at aresectional elevations longitudinal of the feed-table, the planes ofsection being indicated by the lines III III and IV IV of Fig. 5,respectively; and Fig. 5 is a sectional elevation transverse of thefeed-table, the plane of section beingindicated'by the line V V, Figs. 1and 2.

As the' article to be reduced emerges from the pass a of the rolls it isreceived upon a ledge l of the feed-table, arranged in line with saidpass and of such width relative to the cross-sectional dimensions of thearticle as it comes from the rolls that the former will drop off of theledge as soon as it is free of the reducing-rolls and slide down aninclined apron 2 onto feed-rollers 3, which project up through notchesor recesses in the walls of the groove 4 at the lower edge of the apron.These feed-rollers 3 are secured on shafts 5, which are rotated by meansof a suitable power-shaft 6 in such direction as to feed the articleinto the pass b, between the middle and lower reducing-rolls, as shownin Fig. 2. By a suitable feed-table on the opposite side of thereducing-rolls the article is raised and shifted laterally, so as to befed into one or the other of the passes c c, between-the middle andupper reducing-rolls. As the article emerges from these passes it isreceived upon a plate or bed 7, supported by standards 8, having thefeet at their lower ends arranged in suitable guides transverse of thetable, so that the standard and the bed or plate 7 may be shifted intoline with one or the other of the passes o c. To effect the lateraladjustment of the standards 8, an arm 10 on the shaft 11 is connected bya link 1-2 to the standards, so that by the rotation of said shaft byany suitable mechanism, such, for example, as will be hereinafterdescribed, the standard. may be shifted as desired.

On top of the plate or bed 7 is arranged an inverted trough consistingof the L-shaped piece 13 and the side 14, which is hinged to theL-shaped piece, and provided with upwardly-extending arms 15. Ashereinafter stated, the upper ends of these arms 15 are held frommovement transversely of the feedtable, so that when the trough isshifted, as hereinafter described, across the plate or bed 7 the side 14will be turned on its hinge, so as to permit of the discharge of anarticle lying on the plate or bed. The L-shaped portion of the trough isattached to slides 16, which are connected at one end to arms 17 on ashaft 18, said shaft being provided with an operating-handle 19. Bydepressing this handle the slides 16, and with them the box or trough,will be shifted to the left in Fig. 5, so that the article resting onthe plate or bed 7 will be pushed laterally to the edge of such plate,and, as the side 14 is at the same time opened, the article willdropdown the apron 20 into the trough 22 at the lower end of said apronand into grooves in the rollers 23, projecting up through notches in thewalls of the trough 22. These rollers 23 are provided with two grooves,and by the adjustment of the standards 8, which, as hereinbefore stated,carry the bed or plate 7 and apron 22, with its groove, the article canbe dropped into one or the other of the grooves of the rollers 23,dependent upon which one of the passes 01 d the article is to be fedthrough to the front of the mill. The rollers 23 are mounted on theshafts 5,

which are rotated, as hereinbefore stated,by

the power-shaft 6 in such direction as to feed an article resting in thegrooves of said rollers into the reducing-rlls.

On the opposite side of the reducing-rollers suitable mechanism isemployed for lifting the article and shifting the same laterally, sothat it can be fed into one or the other of the grooves e e in the upperand middle reducingrolls. As the article comes from these passes it isreceived upon a plate or bed 24, arranged upon standards 25, havingtheir feet arranged in guide-grooves transverse of the feed-table andadapted to be shifted along said grooves by shaft 26, having arms 27,connected by links to the standards 25. Upon the plate or bed 24 isarranged an inverted trough consisting of an angular strip 29 and a side30, hinged to the angular strip, and provided with arms 31, having theirupper ends connected to suitable mechanism, whereby it is held asagainst movement transversely of the feedtable when the inverted troughis shifted laterally, as hereinafter described. This trough is alsoconnected to the slides 16, so that it can be shifted by the movement ofthe lever 19, in the manner hereinbefore described, in connection with atrough on the plate or bed 7.

In order to hold the upper ends of the arms 15 and 31 stationary, asagainst transverse movement, they are connected to links 32, which inturn are connected by links 33 to posts 34, attached to the standards 8.As the boxes or troughs are shifted by the slides 16 to the left of Fig.the upper ends of the arms and 31 will be held as against such movement,so that the doors 14 and will be turned outwardly, the loose jointbetween the links 32 and 33 permitting of the vertical movement of thesides and the arms attached thereto.

After the article has passed entirely out of the groove c or 6' onto theplate or bed 24 the box or trough resting thereon is shifted to the leftin Fig. 5, thereby opening the side 30 and moving the articletransversely of the plate or bed 24, so that it will drop off of saidbed into one or the other of grooves 35 and 3G in the block 37 and ontorollers 38, provided with suitable grooves and projecting up throughrecesses or slots in the block 37, as clearly shown in Figs. 2, 3, and5. The rollers 38 are secured on the shafts 5, which are rotated by thepower-shaft G in such direction as to feed the article or articles intoone-or the other of the series of grooves f, between the middle andlower reducing-rolls.

It will be found in practice that a mill of the character described isof such capacity that the articles can be reduced with sufficientrapidityin the prior passes to present a second bar or rod for reductionbefore the preceding bar has passed out of one of the passes f, so thatit is necessary to be able to direct the second article as it comes fromthe bed or plate 24 into different grooves in the block 37. This iseffected by means of aprons 39 and 40, one hinged to the standards 25and the other to standards 41, formed integral with or connected to thestandards 25 at their lower ends. These aprons are secured on shafts 42,one of which is rotated by means of a lever 43, attached to the shaft,thereby shifting its apron in or out. The aprons are connected at theirlower edges by yokes 44, passing under the block 37, and so constructedthat when one apron is moved out over one of the grooves in the block 37the other apron will be thrown back, so as to permit the article to dropfreely into the other groove in said block. As shown in Figs. 2 and 5,the grooves in the block 37 are arranged in line with alternate passes fin the reducing-rolls, while the groovesin the feedrollers 38 are inline respectively with the several passes f in the reducing-rolls. Whenthe several parts are in the position shown in Fig. 5, the articles,when they are discharged from the plate or bed 24, will drop into thefirst or third groove in the feed-rollers, dependent upon the positionof the adjustable aprons.

If the standards 25 and 41 be shifted, as hereinbefore described, sothat the trough or box on table 24 will be in line with the pass 2 ofthe reducing-rollers, (see Fig. 1,) the article, when discharged fromthe plate or bed 24, will drop into the second or fourth groove of thefeed-rollers, dependent upon the adjustment of the apron.

I claim herein as my invention-- 1. A feed-table for rolling-millshaving in combination a series of two or more plates or beds forreceiving articles as they come from the reducing-rolls, two or moreinverted boxes or troughs arranged upon the plates or beds, means forsimultaneously moving said boxes or troughs to shift the articleslaterally off of said beds, and two or more series of feedrollers forreceiving the articles as they drop from the receiving-beds and feedingthem to the reducing-rolls, substantially as set forth.

2. A feed-table for rolling-mills, having in combination a series of twoor more plates or beds for receiving articles as they come from thereducing-rolls, means for simultaneously shifting the articles laterallyofi of both beds, two or more series of feed-rollers for receiving thearticles as they drop from the beds, and returning them to thereducing-rolls, and aprons provided with grooves at their lower edgesfor directing the articles as they drop from the beds, and guiding themwhile being fed into the reducing-rolls, substantially as set forth.

3. A feed-table for rolling-mills, having in combination a plate or bedfor receiving articles as they come from the rolls, an inverted box ortrough arranged on the plate or bed, and provided with a movable side,means for shifting the box or trough laterally, arms connected to themovable side, and means for holding the ends of said arms from lateralmovement, substantially as set forth.

4. A feed-table for rolling-mills, having in bed, guide-grooves forreceiving the articles as they drop from the plate or bed, hinged 15aprons for directing the articles into said grooves, yokes connected tothe free edges of the aprons and means for shifting one of the aprons,substantially as set forth.

In testimony whereof I have hereunto set 20 my hand.
